Hydrangea plant named ‘200749077’

ABSTRACT

A new and distinct cultivar of  Hydrangea  plant named ‘200749077’, characterized by its upright and mounded plant habit; strong stems; large durable leaves; large inflorescences; and inflorescences with blue-colored flowers.

Botanical designation: Hydrangea hybrida.

Cultivar denomination: ‘200749077’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Hydrangea plant, botanically known as Hydrangea hybrida, and hereinafter referred to by the cultivar name 200749077.

The new Hydrangea is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands and Glandorf, Germany. The objective of the breeding program was to create new stronger-growing Hydrangeas with attractive flower bract coloration and no vernalization requirement.

The new Hydrangea originated from a cross-pollination conducted in Aalsmeer, The Netherlands on Jul. 20, 1999 of a proprietary selection of Hydrangea hybrida identified as code number 97012-111, not patented, as the female, or seed, parent with a proprietary selection of Hydrangea hybrida identified as code number 98004, not patented, as the male, or pollen, parent. The cultivar 200749077 was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled environment in Glandorf, Germany on Mar. 14, 2001.

Asexual reproduction of the new cultivar by vegetative cuttings at Glandorf, Germany, since Mar. 15, 2003, has shown that the unique features of this new Hydrangea are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar 200749077 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘200749077’. These characteristics in combination distinguish ‘200749077 ’as a new and distinct cultivar:

-   -   1. Upright and mounded plant habit.     -   2. Strong stems.     -   3. Large durable leaves.     -   4. Large inflorescences.     -   5. Inflorescences with blue-colored flowers.

Plants of the new Hydrangea differ from plants of female parent selection primarily in lateral branch thickness as plants of the new Hydrangea have thicker lateral branches than plants of the female parent selection. In addition, plants of the new Hydrangea have darker blue-colored flowers than plants of the female parent selection. Plants of the new Hydrangea differ from plants of male parent selection primarily in flower size as plants of the new Hydrangea have smaller flowers than plants of the male parent selection. In addition, plants of the new Hydrangea have darker blue-colored flowers than plants of the male parent selection.

Plants of the new Hydrangea can be compared to plants of the cultivar Adria, not patented. In side-by-side comparisons conducted in Glandorf, Germany, plants of the new Hydrangea differed from plants of the cultivar Adria in the following characteristics:

-   -   1. Plants of the new Hydrangea were larger and grew faster than         plants of the cultivar Adria.     -   2. Plants of the new Hydrangea were more freely branching than         plants of the cultivar Adria.     -   3. Plants of the new Hydrangea had stronger lateral branches         than plants of the cultivar Adria.     -   4. Plants of the new Hydrangea had larger leaves with longer         petioles than plants of the cultivar Adria.     -   5. Plants of the new Hydrangea were more freely flowering than         plants of the cultivar Adria.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the unique appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Hydrangea. The photograph comprises a side perspective view of a typical plant of ‘200749077’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used in the aforementioned photograph and in the following description were grown in Glandorf, Germany, in 15-cm containers in a glass-covered greenhouse and under conditions which closely approximate commercial production conditions. During the production of the plants, day and night temperatures were about 17° C. Plants of the new hydrangea were grown in a soilless media with a pH level of about 4.4. Plants were about one year old when the photograph and description were taken. The photograph and description were taken during the late winter/early spring.
